Assembly
4.1 Secure the chair to prevent it from rolling
away. Insert the backrest straight into the opening
at the back of the seat until it audibly locks into
place and can no longer be pulled out. Please
note: The gap between the seat and backrest is
required for technical reasons.
4.2 A backlash free connection can be achieved
with the grub screws supplied. Tighten the screws
with a minimal amount of force.
